DOOR STOP SEAL ASSEMBLY Filed June 7, 1962 INVENTOR. TQA/ZJEV 604 /07 75 wlgmaa United States Patent 3,145,517 DGDR STGI SEAL ASSEMBLY Stanley H. Richter, 2327 S. Rio Grande, Orlando, Fla. Filed June 7, 1962, den No. 200,750 1 Claim. (Cl. 20-69) The present invention relates to door stops generally and to a seal for a door stop in particular.

Presently in use are various types of door stop seals for preventing leakage of air and dust between the door stop and door when the door is in closed position. Certain of the seals propose-d and in use comprise resilient elements having a portion thereof seated in a groove provided in the door stop face. Not all of such devices proposed are successful, and one of the reasons for failure of some of the devices is that they tend to split away from the stem portion which is seated in the groove after repeated use.

Other devices having stems seated in grooves are usually pulled from the grooves after a period of wear due to the nature of the material used to fabricate the resilient strip.

An object of the present invention is to provide a door stop seal assembly in which the resilient sealing member may not with ordinary force be pulled from the groove in which it is seated, nor will the door stop strip split due to pulling pressure applied to the sealing member.

Another object of the present invention is to provide a door stop seal assembly which employs an extruded resilient seal economical to manufacture, and employs a wooden door stop which is fabricated economically and Without the need of special tools.

A further object of the present invention is to provide a door stop seal assembly which is efficient in operation, one foolproof in operation, one which is easy to install, one having long life characteristics, and one which is economically feasible.

These and other objects and advantages of the present invention will be fully apparent from the following description when taken in connection with the annexed drawing, in which:

FIGURE 1 is a vertical view in section of a door substituting door jambs, showing the door stop seal assembly of the present invention in position sealing the door,

FIGURE 2 is a view taken on the line 22 of FIG- URE 1,

FIGURE 3-is a view on an enlarged scale, taken on the line 33 of FIGURE 2,

FIGURE 4 is a perspective view of a section of the assembly according to the present invention, and

FIGURE 5 is a perspective view of a portion of the door stop with the sealing member of the present invention removed therefrom.

Referring in detail to the drawing in which like numerals indicate like parts throughout the several views, the door stop seal assembly of the present invention comprises an elongated wooden strip having at least one flat edge 12.

The edge 12 may be described as having a groove 14 which is substantially cruciform in crosss sectional outline. In other words the groove 14 has straight side walls 16 and i8 and a bottom wall 20. Each of the side walls 16 and 18 is provided intermediate its ends with a recess 22, 24 respectively. Each of the recesses 22 and 24 has the wall 26, 28, respectively, adjacent the edge 12 sloping at an angle to the edge 12. The opposite wall 30 of the recess 22 and the wall 32 of the recess 24 are substantially parallel to the face 12, as shown most clearly in FIGURE 5.

The present invention provides a resilient member 34, elongated, and fabricated in the same length as the strip 10.

3,14%,517 Patented July 14, 1964 ice The member 34 is hollow and has a convex outer wall 36 and an inner wall 38.

A stem 40 projects outwardly of the inner wall 38 along the longitudinal center line of the inner wall 38.

The stem 4% is conformably shaped to substantially fit within the groove 14 in the strip 10 with a wing portion received in each recess and with an anchor portion extending into the space between the recesses 22 and Z4 and the groove bottom wall 20.

It will be seen therefore that the parts of the stem 40 of the resilient member 34 which extend into the recesses 22 and 24 form shoulders 42 and 44, respectively, which prevent the pulling out of the stem 40 from the groove 14, by any straight forward pull or by any pull to one side or the other of the resilient member 34.

An important feature resides in the fact that, as shown in FIGURE 4, the inner wall 33 is spaced from the edge 12, as at 46, when the overlapping side edges 48 of the convex wall 36 abut against the edge 12.

This provides an additional cushion and adds resiliency to the member 34.

It will be also noted in FIGURE 3 that the wall 38 is thicker in the center than along the side edges and this added thickness to the wall 38 strengthens the member 34 against pulling out of the groove 14. Also the added thickness of the wall 38 resists tearing out of the wall 38 at the point of connection with the stem 40.

Preferably, as shown in FIGURE 3, the groove 14 is formed in the portion of the strip 10 remote from the jarnb 55 to which the strip 15 is attached.

The strip 10 is secured by nailing or other suitable means to the door jarnb 50 or header of a frame adjacent a door 52 so that the member 34 is sealingly engaged by the door 52 when the door 52 is in the closed position as shown in FIGURE 1.

Preferably, as shown in FIGURE 3, the member 34 is positioned adjacent the outer face of the strip 10 and remote from the jamb or header 50.

In such a position the member 34 will resiliently engage the door 52 and seal the space between the strip lit and the door 52 against the passage of air in quantity.

The teaching of the invention resides in the shape of the groove 14 and the shape of the stem 40 of the resilient member 34. This shape being such that it resists pulling from the groove 14 under conditions of ordinary use or abuse.

While only a preferred embodiment of the present invention has been shown and described, other embodiments are contemplated and numerous changes and modifications may be made without departing from the spirit of the invention as set forth in the appended claims.

What is claimed is:

In a door stop seal assembly, the combination comprising an elongated strip having a groove extending inwardly from one edge of said strip, said groove having fiat side walls and bottom Wall, said strip including a pair of recesses each extending substantially orthogonally and inwardly from a respective one of said side walls intermediate the ends thereof, an elongated resilient seal member having a convex outer wall and an inner Wall, said inner wall secured to said outer wall at points spaced from the ends thereof to provide a pair of overlapping side edges engaging the edge of said strip and maintaining said inner wall spaced from the edge of said strip, a stem projecting from the longitudinal center line of said inner wall, said stern having a wing portion on each side thereof conformably shaped to and received in a respective one of the recesses, said stem having an anchor portion adjacent the free end thereof conformably shaped to and extending into the space between said recesses and said groove bottom wall, the cross-sectional area of said groove and recesses being as nearly as practical equal to the cross-sectional area of said stem, wing portions, and anchor portion, said anchor portion being of a size to engage between and prevent folding of said wing portions toward each other upon the application of an outwardly pulling force to said seal member to thereby prevent outward movement of said stem from said groove.
